Why are my contributions removed? I work at a manufacturer of high security locks and I contributed our lock firm to the manufacturers and our locks to the high security locks and next day they are removed again without any notice or explanation. Do I have to pay to be mentioned here or what is going on? Our locks are VdS class B, IMP, ECB-S EN1300 Class B and UL certified so don't tell me we don't belong in those groups.
